AMobile office

BWireless medical

CRail transit

DVideo return

Answer : D

Question 4

In the WLAN coverage, the accuracy of wireless positioning is closely related to AP signal coverage.

ATrue

BFalse

Answer : A

Question 5

Which of the following networking methods are recommended for outdoor WDS planning?

ARoot against four leaves

BOne-hop relay between root and leaf

CTwo-hop relay between root and leaf

DRoots against eight leaves

Answer : A, B, C

Question 6

The following description of the BYOD networking of large enterprises is wrong?

AThe network is divided into access layer, distribution layer and core layer.

BAP is connected to the access layer switch. It is recommended to use a PoE switch.

CAC can be implemented using the built-in AC card of the core switch.

DAt the access layer, you can use the side-mounted CA to implement wireless centralized control.

Answer : D

Question 7

Basic requirements for WLAN network construction include bandwidth requirements, coverage targets, coverage methods, field strength requirements, and power distribution methods.

Determining the strength of the coverage area in the field strength requirement is adjusted by the AP transmit power. The following statements are correct regarding the requirements that the network regulation needs to consider in advance.

Is it?

AThe field strength demand in key areas is that the main online area of the user can be controlled at -40~-80dBm. If the power is too strong, it will easily lead to receiving overload, and the power is too weak.
Will cause the connection rate to drop

BThe interference field strength requirement is that the same-frequency interference in the same area is not more than -80dBm

CThe fringe field strength level combined with the receiving sensitivity and edge bandwidth requirements are generally selected above -75dBm

DThe leakage field strength of the system should not be too large, and the field strength at 10m of the external network of the building cannot be greater than -90dBm.

Answer : B, C, D
